"Another parable put he forth unto them, saying, The kingdom of heaven is like to a grain of mustard seed, which a man took, and sowed in his field:
Which indeed is the least of all seeds: but when it is grown, it is the greatest among herbs, and becometh a tree, so that the birds of the air come and lodge in the branches thereof."
TBC: This passage of Scripture is one of a number favored by Skeptics who gleefully point out that Jesus didn't know what He was talking about when he said mustard seeds are the smallest seeds. They are quick to point out that there are a number of seeds worldwide (such as the orchid) which are smaller than mustard.
Had the skeptics simply read the passage and thought about what it actually said, this supposed difficulty would quickly escape their grasp. Speaking to a specific group, the Lord Jesus uses language which is easily understood. Jesus specifically says that these seeds are those "which a man took, and sowed in his field." Since the farmer would not be sowing orchids in his field (if indeed he knew what an orchid was), the parable Jesus told would have little meaning, if any, to him. Finally, the black mustard seed planted in Israel to this day will grow sometimes to an height of 12 feet, something also challenged in the Lord's narrative.
